Air Flotation Wastewater Treatment Machine

Air Flotation Wastewater Treatment Machine

At present, it has applications in water supply, industrial wastewater and urban sewage treatment. Compared with other solid-liquid separation equipment, air flotation equipment has the characteristics of less investment, very small footprint, high degree of automation, and convenient operation and management. In practice, targeted selection and use should be made according to the characteristics of wastewater treatment process, wastewater quality and quantity. 

Air flotation equipment is a type of air flotation equipment that passes in or generates a large number of fine bubbles in the water, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. It uses the principle of buoyancy to make it float on the water surface. Water treatment equipment that realizes solid-liquid separation. Air flotation methods can be divided into diffuse air flotation, dissolved air flotation (including vacuum air flotation) and electrolytic air flotation. In sewage treatment technology, air flotation is used in several aspects:
⑴ Oil-water separation of oily sewage in petroleum, chemical and machinery manufacturing
⑵Industrial wastewater treatment
⑶ Recovery of useful substances in sewage
⑷Replace the secondary sedimentation tank, especially for the situation that is prone to swelling of activated sludge
⑸Concentration of excess activated sludge
2.2 Process characteristics and scope of application of air flotation equipment
2.2.1 Process characteristics of air flotation equipment
At present, the air flotation device of the pressure dissolved air flotation method is the most widely used. Compared with other air flotation devices, the air flotation equipment has the following advantages:
⑴ Under pressurized conditions, the solubility of air is large, and the number of bubbles for air flotation is large, which can ensure the air flotation effect;
⑵The dissolved gas is released after sudden decompression, and the bubbles produced are not only fine, uniform in particle size, large in density, but also floating and stable, with little disturbance to the liquid, so it is especially suitable for the solid-liquid separation of loose flocs and fine particles;
⑶The process and equipment of the air flotation equipment are relatively simple, easy to manage and maintain.
